Gym and health club contracts are notoriously stringent and difficult to break, and have often been the subject of class action lawsuits and other litigation. But like other properly-executed contracts, gym and health club contracts are generally enforceable unless they are unconscionable as a matter of law (this is rare) or include provisions that are prohibited by law. Most states have specific laws (statutes) that limit the terms that may be included in gym and health club contracts—and if such a contract does not comply with the state’s laws, it is likely void and unenforceable—at least in part.

In California, gym and health club contracts are regulated by the California Health Studio Services Contract Law, which is found in the California Civil Code starting at Section 1812.80. This law sets forth specific requirements and limitations for contracts between consumers and health studio services, which include gyms and health clubs. For instance, these contracts cannot exceed a term of three years, and they must provide a right to cancel under certain conditions, such as moving a specified distance away from the facility or upon a doctor's order due to physical disability. Additionally, the law mandates a five-day right to cancel the contract after signing. If a gym or health club contract does not adhere to these statutory requirements, it may be considered void and unenforceable. However, if the contract is properly executed and complies with the law, it is generally enforceable unless it is found to be unconscionable or contains illegal provisions.
